Your complete guide to a clean submission, with the new Income Tax Reference Number rule, the most common rejection reasons, and what happens if you miss the deadline.
If you employ even one person in South Africa, you have an EMP501 to submit by 31 May. With 31 May falling on a Sunday in 2026, the practical deadline is Friday 29 May. Get it wrong and SARS can charge you up to 10% of your annual PAYE liability. Get it late and your employees cannot file their own tax returns. Here is everything you need to do, and how to do it cleanly.
This guide walks through what the EMP501 is, what makes a clean submission, what is new this year, what to do if your submission is rejected, and how to get back on track if you have already missed the date. It is written for South African employers managing payroll themselves, and for those working with bookkeepers or payroll providers who want to understand what is happening on their behalf.
⚑ IF YOU DO ONE THING THIS MONTH
Get every employee registered for income tax
From the 2026 filing season, SARS will not accept an EMP501 submission unless every employee on it has a valid Income Tax Reference Number. One missing tax number blocks the entire submission.
This is not a per employee rejection. The whole file fails. You can have 499 employees registered and one who is not, and SARS will still refuse to accept your reconciliation. The deadline does not pause while you sort the registration out.
Employee tax registration runs through eFiling or e@syFile Employer using ITREG (single employee) or BundleReg (multiple employees). Both are free. Both can take a few working days to come back. Leaving this for the deadline week is the single biggest avoidable risk in the EMP501 process.

What is the EMP501?
The EMP501 is the Employer Annual Reconciliation Declaration. It is the document that ties together three things: your twelve monthly EMP201 declarations, the actual payments you have made to SARS for PAYE, UIF, and SDL, and the IRP5 and IT3(a) tax certificates issued to your employees for the tax year ending 28 February.
Those three figures must reconcile. Where your monthly EMP201s show that R600,000 in PAYE was due over the year, your payment records show R600,000 paid, and your employee certificates total R600,000 in PAYE deducted, your EMP501 reconciles cleanly. Where any of those numbers disagree, SARS knows there is a problem before you do.
The EMP501 covers the full tax year, from 1 March 2025 to 28 February 2026. Submission opens on 1 April and closes on 31 May. The window is two months, although in practice many employers leave it to the final fortnight, which is when the SARS systems become heavily congested.
What is new in 2026
This filing season brings one significant change that catches employers off guard. SARS will reject any EMP501 that contains employees without a valid Income Tax Reference Number.
In previous years, you could submit IRP5 certificates for employees who were not yet registered for income tax, with a placeholder code in the tax number field. From 2026 onwards, that route is closed. Every employee on your reconciliation must have a valid Income Tax Reference Number recorded against their certificate. Where they do not, the entire submission is rejected.
Put another way: no employer can press send on an EMP501 with even one employee missing a valid Income Tax Reference Number. It does not matter how large or small the workforce is. One unregistered employee out of one, ten, or five hundred holds the entire submission back.
This rule was published well in advance, although it has caught out plenty of employers in the first weeks of the filing season. Where you have new employees, casual workers, or anyone hired during the year who has not yet registered for personal income tax, this needs to be sorted out before submission. Two paths are available.
- Individual Income Tax Registration (Individual ITREG) on SARS e@syFile Employer, for one employee at a time
- Bundled Income Tax Registration (Bundled ITREG), for multiple employees at once
Both options are free, both run through e@syFile, and both can take a few working days to complete. Leaving this work for the week of the deadline is risky. Sort it out as early as possible.
⚑ SARS Rule: EMP501 submissions without valid Income Tax Reference Numbers for every employee will not be accepted. This is a hard rule, not a warning. Plan registration work for early in the submission window, never the deadline week.
What goes into a clean submission
A clean EMP501 submission has five elements working together. Where any one of them is off, the reconciliation fails.
1. Twelve accurate EMP201 monthly declarations
Each month from March to February should have a corresponding EMP201 declaration showing PAYE, UIF, and SDL liability for that month, plus any ETI claimed. Where you have missed an EMP201 anywhere in the year, that needs to be submitted before the EMP501 can reconcile.
2. Payments matching what was declared
The actual payments you made to SARS each month, excluding penalty and interest payments, must match the totals on your EMP201s. SARS pulls the payment data automatically from their side. Where there is a difference between what you declared and what you paid, the reconciliation will not balance.
3. IRP5 and IT3(a) certificates for every employee
Every employee who earned income from you during the tax year needs an IRP5 (where PAYE was deducted) or an IT3(a) (where it was not). The total PAYE on the certificates must match the total of your monthly EMP201s. Each certificate must include the employee’s valid Income Tax Reference Number.
4. ETI claims supported and reconciled
Where you claimed Employment Tax Incentive during the year, those claims need to be supported by accurate employee data, including dates of employment, ages, and minimum wage compliance. SARS audits ETI claims closely, and incorrect or unsupported claims are clawed back with interest.
5. Submission via e@syFile or eFiling
Most employers submit through SARS e@syFile Employer, which is the dedicated software for employer reconciliations. Smaller employers (with five or fewer certificates) can submit through eFiling. The latest version of e@syFile is required for the 2026 reconciliation. Older versions will not work.
The most common rejection reasons
In a typical filing season, SARS rejects between 10% and 15% of EMP501 submissions on first attempt. The reasons cluster around the same handful of issues.
- Missing or invalid Income Tax Reference Numbers on employee certificates (the new 2026 rule)
- EMP201 totals not matching certificate totals (often caused by a missed monthly submission)
- Payment totals not matching declared totals (often caused by a deferred or split payment)
- Incorrect ETI claims, including claims for ineligible employees or amounts above the legislated maximum
- Submitting through an outdated version of e@syFile or eFiling
A rejected submission is treated as not submitted. This matters because the deadline does not pause for a fix. Where you submit on Friday 29 May and the file is rejected over the weekend, the resubmission needs to be in by 31 May, with no working hours available to chase down a missing tax number or a payroll mismatch. Anything submitted after 31 May, even of a corrected file, is treated as late and penalties apply from the original deadline.
The lesson is the same every year. Submit early, leave room to fix what comes back.
What happens if you miss the EMP501 deadline
Late or non submission of an EMP501 carries three layers of cost.
Administrative penalty
SARS can impose a penalty of 1% of the total employee tax for the reconciliation period, charged each month the submission is outstanding, up to a maximum of 10%. For an employer with R1 million in annual PAYE, that is up to R100,000 in penalties alone.
Interest on outstanding amounts
Where the late submission also reveals underpaid PAYE, UIF, or SDL, interest accrues on the outstanding amounts at the prescribed SARS rate, currently around 10.75% per annum. Interest runs from the original due date of the underlying monthly payment, not from the EMP501 deadline.
Blocked employee tax certificates
This is the consequence many employers do not anticipate. Until your EMP501 is submitted and accepted, your employees cannot access their IRP5 certificates on eFiling. That means they cannot file their own tax returns when filing season opens in July. Your compliance failure becomes their problem, and that is a conversation no employer wants to have.
In serious or repeated cases, SARS can also pursue criminal prosecution under the Tax Administration Act, with directors held personally liable. This is rare in practice. The financial penalties alone are usually severe enough to focus the mind.
If you have already missed the deadline
Submit anyway. Submit today. The penalty stops accruing the moment the submission is in. Every additional month the EMP501 remains outstanding adds another 1%, up to the 10% ceiling.
Where the late submission was caused by genuine difficulty, including illness, system failures, or other circumstances outside your control, you can submit a Request for Remission (RFR) to SARS once the EMP501 has been filed. The RFR asks SARS to reduce or remove the penalty. SARS reviews each request individually, and a clear explanation supported by evidence makes a meaningful difference.
What does not work is silence. Ignoring an outstanding EMP501 leads to estimated assessments, escalating penalties, and eventually compliance enforcement. Submitting late is significantly better than submitting never.
Practical timeline for the rest of May
Where you have not yet started, here is a workable plan for the remaining days of the filing window. One important note before the schedule: 31 May 2026 falls on a Sunday. While SARS systems may technically accept submissions over the weekend, the practical deadline for any sensible employer is Friday 29 May. The plan below builds towards that date, with the weekend reserved as a buffer for handling any last minute rejections.
This week
- Pull your monthly EMP201 records and confirm all twelve are submitted
- Run an Income Tax Reference Number check on every employee
- Submit Individual or Bundled ITREG for any employee without a valid number
Next week
- Generate IRP5 and IT3(a) certificates from your payroll system
- Reconcile EMP201 totals to certificate totals to payment totals
- Resolve any differences. Each one is a rejection waiting to happen
Final week
- Download the latest e@syFile Employer version
- Import your data and run e@syFile’s built in validations
- Submit by Friday 29 May. Treat the weekend as a buffer for handling rejections, not as a submission window
